-LRB- CNN -RRB- -- A decade after Elizabeth Smart 's kidnapping ended , she is sharing intimate details of her 9-month-long nightmare .

Smart , now 25 and married , spoke to CNN 's Anderson Cooper Monday about her book `` My Story , '' which she said tells 100 % of what happened to her .

`` I did n't just want to go 10 % and sugarcoat the rest , '' Smart told Cooper . `` I wanted it to be really what happened and what it was like every single day I was there , because I do n't think I 'm doing anyone any favors by sugarcoating it . ''

Her motivation for opening up is the realization that people do n't often acknowledge the `` just staggering '' fact that one in four girls and one in six boys are sexually abused before age 18 .

`` I want to reach out to those survivors and those victims , '' Smart said . `` I want them to know that these things do happen , but that does n't mean that we have to be defined by it for the rest of your life . You can move forward and you can be happy . ''

Smart 's abduction

Smart 's horrific story began on the night of June 5 , 2002 , when Brian David Mitchell dragged the 14-year-old from her bedroom in her family 's Salt Lake City home .

`` To me , in my bedroom is the ultimate place in safety , '' she said . `` I mean , I felt like that was the safest place in the world for me , so waking up in the middle of the night in my own bedroom having this strange man standing over me , someone I did n't recognize , not only that but having a knife being held to my throat , I was terrified . I had grown up in a very happy home and I really did n't know what the definition of fear was until that moment . That brought whole new meaning . ''

The street preacher threatened the child unless she left with him quietly , she said .

`` He said ' I have a knife at your neck , do n't make a sound , get up and come with me , ' '' Smart told Cooper . `` And then I remember getting up and going with him , and then on the way through my house he bent over to my ear again and said ` If you make any sound , if you do anything that causes any attention or causes someone to come , I not only will kill you , but I will kill anyone who tries to stop me . ' ''

Smart described the first hours of her ordeal , when she was `` praying so hard for an escape . ''

`` I kept looking , I kept waiting for something to happen , for some way for me to get away , '' she said . `` I kept looking and it did n't happen . When I did n't see an escape route , I thought ` Oh , my goodness , I 'm going to be raped and then I 'm going to be murdered , because that 's what happens to all of the other kids I 've ever seen on the news who had been kidnapped . ''

Mitchell forced her to hike with him for hours that morning , away from her home , she said .

`` I remember stopping him and asking him ` Well , if you 're going to rape and kill me , could you please do it here ? ' because , in my mind , I wanted my parents to know what had happened to me , '' she said . `` I wanted them to know that I had n't run away , that this was n't my choosing , I was n't upset with them . I wanted them to know what had happened to me . ''

Mitchell 's response was chilling .

`` I remember he just looked back at me and said , ` Oh , I 'm not going to rape and kill you yet . ' And then we kept going and I remember we got a little further and I stopped him again and I said ` Well , do n't you realize what you 're doing , I mean , if you get caught you 'll spend the rest of your life in prison ? ' And he looked at me again and he said , ` Well , I know exactly what I 'm doing and I know what the consequences are . The only difference is I 'm not going to get caught . ' ''

After several hours , they arrived in a mountainside camp where Mitchell 's wife , Wanda Barzee , was waiting .

`` I was terrified when I got to the camp , but the scariest thing about the camp was this woman , '' she said . `` I remember she came out and she had on robes and she had on a headdress and she came up to me and she hugged me . But this hug was not comforting . I mean , if hugs could speak this hug would have said , ` You 're mine , you will do exactly what I tell you to do . ' ''

Nine months of terror

The constant sexual abuse by Mitchell began that day .

`` The next nine months , my days consisted of being hungry , of being bored to death because he talked nonstop always about himself , '' she said . `` I mean , talk about self-absorbed . And then my days consisted of being raped . I mean , not just once , multiple times a day . ''

While Smart 's story is about hope and survival , the details are filled with despair .

`` Every time I thought ` OK , this is rock bottom , ' I mean , my pajamas have been taken away from me and I 'm being forced to wear this nasty robe , the next thing I knew they 'd say , ` We 're going to have you go naked now , ' or I had been forced to drink alcohol , which I had never done before , '' she told Cooper . `` I would throw up and I would pass out and when I 'd wake up I 'd find that my face and my hair was just crusted to the ground in vomit . I mean , just every time I thought it could n't get worse , something always happened . ''

Smart said she eventually decided she would be a survivor and she would get back to her family .

Smart 's rescue on March 12 , 2003 , was followed by second-guessing by people who wondered why she had n't escaped on her own . Why had she told a detective who talked to her at a library that she was not the kidnapped girl ?

Smart : Never judge a victim

`` You can never judge a child or a victim of any crime on what they should have done , because you were n't there and you do n't know and you have no right just to sit in your armchair at home and say ` Well , why did n't you escape ? Why did n't you do this ? ' I mean , they just do n't know , '' she said . `` That 's wrong . And I was 14 . I was a little girl . And I had seen this man successfully kidnap me , he successfully chained me up , he successfully raped me , he successfully did all of these things . What was to say that he would n't kill me when he 'd make those threats to me ? What was to say that he would n't kill my family ? ''

The second half of Smart 's interview with Cooper , in which she reveals details of how she was rescued , will air on CNN 's `` Anderson Cooper 360 '' Tuesday night .
